Abstract
The utility model provides a laser-etched main shaft bushing. The laser-etched main shaft bushing comprises a tile-shaped upper main shaft bushing and a tile-shaped lower main shaft bushing, which are oppositely arranged, wherein the upper main shaft bushing and the lower main shaft bushing are both formed by a steel backing as outer ring and a bearing alloy layer as inner ring respectively, lubricating oil linear grooves are arranged on the inner side surfaces of the bearing alloy layers, and stopping edges are arranged on the two sides of the opening of the upper main shaft bushing and on the two sides of the opening of the lower main shaft bushing respectively. The lubricating oil linear grooves are distributed in a honeycomb shape on the inner side surfaces of the bearing alloy layers of the upper and the lower main shaft bushings, and the lubricating oil linear grooves are isolated from one another. The laser-etched main shaft bushing has simple structure and practical function, the production procedures and the production cost are reduced, and the load-bearing capacity and the service life of the main shaft bushing are improved.
Description
Technical field
The utility model relates to a kind of laser and carves and chisel main axle bush.
Background technique
Along with motor at a high speed, carry by force, direction such as energy-conservation, efficient develops, the requirement of main axle bush is improved constantly.Require bearing shell to have big bearing capacity and fatigue strength, will have good seizure resistance, allowing property of embedding, compliance, anti-corrosion property, compressive strength and antifriction quality simultaneously.The top bearing shell that is designed to of general engine spindle watt is respectively the split setting with top bearing shell thrust plate, lower bearing and lower bearing thrust plate or fixedlys connected.The bearing shell thrust plate is easy to come off, and bearing capacity can not be very big, and compressive strength is also lower, and greasy property is not so good, and the machining accuracy and the manufacturing procedure of requirement are more, the cost of production height.
The model utility content
The utility model purpose is to provide a kind of laser to carve to chisel main axle bush, long service life, save cost, bearing capacity is big.
To achieve these goals, the utility model adopts following technological scheme: a kind of laser is carved and is chiseled main axle bush, comprise the last main axle bush of watt shape that counterpart is provided with and lower main axis watt, last main axle bush and lower main axis watt are formed by the steel backing of outer ring and the bearing alloy layer of inner ring, the bearing alloy layer inner side surface is provided with the lubricant oil wire casing, and the opening both sides of last main axle bush and lower main axis watt are provided with the thrust side respectively.
The described bearing alloy layer inner side surface of going up main axle bush and lower main axis watt is provided with cellular lubricant oil wire casing, and each lubricant oil wire casing does not connect mutually.
Between the described bearing alloy layer of going up main axle bush and lower main axis watt and the steel backing be connected to that casting is connected, sintering connection or rolling connection.
Described lubricant oil wire casing is rectangle, circle, rhombus.
Described bearing alloy layer is acieral or copper base alloy.
Described thrust side and the last main axle bush of going up the opening both sides of main axle bush is stamping forming integrative-structure, and the thrust side of the opening both sides of lower main axis watt and lower main axis watt are stamping forming integrative-structure.
The utility model adopts laser to carve on bearing alloy layer to chisel machine engraving to chisel uniform lubricant oil wire casing, and each lubricated wire casing do not connect mutually, makes bent axle when moving the commentaries on classics, form liquid friction (fluid friction) with the friction of main axle bush thus improve antifriction quality.Wherein carving the lubricant oil wire casing of chiseling on the thrust side can stop lubricant oil to flow away fast.The main axle bush both sides are provided with the thrust side, and two thrust sides all are impact briquettings, have reduced production process and cost of production, have improved bearing capacity, the working life of main axle bush.

Embodiment
Embodiment: shown in Fig. 1-4, a kind of laser is carved and is chiseled main axle bush, comprise the last main axle bush of watt shape that counterpart is provided with and lower main axis watt, last main axle bush and lower main axis watt are formed by the steel backing 1 of outer ring and the bearing alloy layer 2 of inner ring, adopting laser to carve on bearing alloy layer 2 inner side surfaces to chisel machine engraving to chisel has the lubricant oil of wire wire casing 3, and the opening both sides of last main axle bush and lower main axis watt are provided with thrust side 4 respectively.The thrust side of the opening both sides of last main axle bush and last main axle bush are stamping forming integrative-structure, and the thrust side of the opening both sides of lower main axis watt and lower main axis watt are stamping forming integrative-structure.Between the bearing alloy layer 2 of last main axle bush and lower main axis watt and the steel backing 1 be connected to that casting is connected, sintering connection or rolling connection, bearing alloy layer 2 is acieral or copper base alloy.Bearing alloy layer 2 inner side surfaces of last main axle bush and lower main axis watt are provided with cellular lubricant oil wire casing 3, and each lubricant oil wire casing 3 does not connect mutually.Lubricant oil wire casing 3 is rectangle, circle, rhombus.
During concrete enforcement, adopting laser to carve on bearing alloy layer to chisel machine engraving to chisel has uniform lubricant oil wire casing, and each lubricated wire casing do not connect mutually, makes bent axle when moving the commentaries on classics, form liquid friction (fluid friction) with the friction of main axle bush thus improve antifriction quality.Wherein carving the lubricant oil wire casing of chiseling on the thrust side can stop lubricant oil to flow away fast.The main axle bush both sides are provided with the thrust side, and two thrust sides all are impact briquettings, have reduced production process and cost of production, have improved bearing capacity, the working life of main axle bush.
